[Kea-users] Ignore non-reserved hosts

[Mark Moseley]

I've been scouring the manual and google for this but have finally reached
the point of giving up and bugging the list :)

I'm trying to migrate our DHCP from dhcpd to Kea. I've got an existing DHCP
server that it will need to live alongside Kea for a little bit. Server is
Ubuntu Focal, with Kea 1.8.2, with mysql host reservation backend.

I've been trying to figure out how to tell Kea to ignore any hosts that
don't appear in the host reservation. I.e. I want Kea to only respond to
DHCP requests from MAC addresses that I have configured in the Kea MySQL
'hosts' table.

Currently, Kea is churning out a steady stream of DHCP NAK's to the
non-reserved hosts (which are 'reserved' on the legacy dhcpd server but
will eventually be migrated to Kea), when those hosts renew their lease.
I'd like Kea to silently drop the unrecognized DHCP requests.

I think this would be the equivalent of dhcpd's "deny unknown-clients".
keama didn't know what to do with that directive (it created a 'statement'
clause that kea-dhcpd4 did not recognize).

Is it doable/possible to configure Kea to ignore any hosts that don't
appear in the host reservations?

Thanks!
